الصف : الحادي عشر - العام الدراسي : 2015/2016


Once upon a time, and during the Earth's history, a group of reptiles is named "dinosaurs" have ruled the planet. Dinosaurs were the largest terrestrial creatures have ever ruled the Earth but from about sixty-five million years ago the dinosaurs died out, along with over than 50% from other creatures all over the world from unknown causes.



SO ;



1)- What was the cause of that mass extinction ?



2)- How did scientists discover dinosaurs and know about their extinction ?



3)-Why did some species survive and dinosaurs didn’t although they were the strongest creatures during  that  period ?



I will try to answer those questions in this seminar and I hope it will be an exciting research for you…
